Answer:

x=3

Step-by-step explanation:

First we will distribute the 4 into the (x+7) and 9 into (x-1).

You should then got

4x+28=9x-9+22

Afterwards we combine like-terms

4x+28=9x+13

Then, we put all the alike values on the same side together.

4x+28=9x+13

-4x -4x

___________

28=5x+13

-13 -13

____________

15=5x

You then divide both sides by 5 to isolate x

15/5= 3

x=3

marshall27 [118]

Answer:

x ≥ 5, 8.25x + 10 = 175, and x = 20 hours.

Step-by-step explanation:

Let Lin works x hours per week.

Now given that Lin’s job pays $8.25 an hour plus $10 of transportation allowance each week.

And she has to work at least 5 hours a week to $175 per week.

So, the inequality that can be written from the above condition is x ≥ 5 .......(1)

And the equation that can be written that

8.25x + 10 = 175 ....... (2)

Now, fro equation (2) we can write x = 20 hours which satisfies equation (1).

Suppose the radius of a circle is 8. What is its area?

monitta

The Formula to find the Area of a circle using the radius is:
$A = \pi r^2$

r = 8
So:
$A = \pi r^2$
$A = \pi 8^2$
$A = \pi64$

And you get about 201.06193

So, the area of a circle with a radius of 8 is about 201.06

Hope this Helps :)
